Abstract
Abstract A radiant heat boiler comprises a heat insulated enclosure adapted to maintain a sub-atmospheric pressure. Radiant heat reflecting surfaces are arranged as the faces of a regular polybedron on the inner surfaces of the enclosure. A pressure vessel is centrally situated within the polybedral enclosure in spaced relation to the reflecting surfaces. The vessel is provided with a fluid inlet and a fluid outlet. A localized radiant heat source, such as a radiant heat lamp, is mounted within the enclosure in the space between the reflecting surfaces and the pressure vessel. The pressure vessel may be transparent or opaque. If transparent, radiant heat absorbtive plates may be provided within the vessel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
112 words
A radiant heat boiler which comprises a hollow hermetically-sealed, heat-insulated enclosure, the interior of which is evacuated to a subatmospheric pressure, said enclosure having a substantially globular inner surface; radiant heat reflecting surfaces covering the inner surface of the enclosure; a hollow substantially globular pressure vessel centrally situated within said enclosure, said vessel including an outer shell provided with a fluid inlet means and a fluid outlet means, said pressure vessel having its outer shell about the entire periphery thereof spaced apart from the reflecting surfaces; and at least one localized radiant heat source within the enclosure in the space between the reflecting surfaces and the outer shell of the pressure vessel.
Claim 2
Dependent Claim
112 words
A radiant heat boiler which comprises a hollow hermetically-sealed, heat-insulated enclosure, the interior of which is evacuated to a subatmospheric pressure, said enclosure having a substantially globular inner surface; radiant heat reflecting surfaces covering the inner surface of the enclosure; a hollow substantially globular pressure vessel centrally situated within said enclosure, said vessel including an outer shell provided with a fluid inlet means and a fluid outlet means, said pressure vessel having its outer shell about the entire periphery thereof spaced apart from the reflecting surfaces; and at least one localized radiant heat source within the enclosure in the space between the reflecting surfaces and the outer shell of the pressure vessel.
